Eve

 A little girl is standing in front of her home by herself.

She is not dressed properly for the weather. A couple, out exercising, spot her and ask why she is standing there. They take her to see her father.

The father is sitting on the swing set in the backyard.

When they approach him, they discover he is pale from lose of blood. He has two puncture wounds in his neck. The little girl screams. 

 Mulder believes the case has similarity to cattle exsanguinations. Only this time it is a human. It may have UFO ties.

Talking to the little girl, Teena, she claims “people from the clouds” wanted to exsanguinate her father.

She is now an orphan. While talking to her, Scully gets a call that a similar murder has happened on the other side of the country.

 The other girl, Cindy, looks exactly like her.

Cindy’s father has died the exact same way. Cindy’s mother reveals that she had used in vitro fertilization.

 Meanwhile, Teena has been kidnapped.

 Mulder and Scully discover that both sets of parents had used the same fertility clinic.

They also discover it was the same doctor. The doctor had been fired for experimentation. They believe this Doctor Sally Kendrick may be the kidnapper and murderer.

Mulder receives a tip from Deep Throat. The government had experimented with eugenics. There had been several identical children. The boys were called Adam. The girls were called Eve. Dr, Kendrick was one of the Eves. They meet another in a prison for the mentally insane.

Dr. Kendrick has continued the program.

Cindy and Teena are the product. They too, have the homicidal tendencies that the Eves had.

 Cindy and Teena just knew about each other and how to plan the identical murders.

We just knew.
